15mm copper tails to old 15mm tap connectors?

[drongo22]

Hi I am needing to connect new basin tails to existing flexi hoses, the flexis are buried behind tiles so I only have access to the 22mm female ends that connected to the old taps. Can I remove the nut and olive from one side of two isolation valves then connect the old female ends of the flexis then connect the remaining sides to the new 15mm tails?

Thanks in advance!

Yes you can, but I would never leave flexis buried inside a tiled wall. Seen too many bursts to stop using them.
